Because celebrities are constantly in the public eye, it's always surprising when you find out they've been up to something unexpected behind the scenes.

The end goal is to make more money than the amount you put into it, but that's never guaranteed. It's a risky business, but for some celebs it's really worked out (read: really, really worked out).
